Gracie jumps better, but is miles behind when it comes to performing.
I wasn't impressed by Polina when I saw them side by side 2 years ago. I thought she was middle of the pack forgettable. I hope I'm wrong.

No. She's only 15 years old. But that means she'll be 19 by PyeongChang.

Lower age limit is that the skater must be 15 by the July 1st prior to the season in which to compete in Worlds/Europeans/Four Continents/Olympics. Polina was 15 on May 18th, 2013. She makes it by a bit more than a month. She's eligible.

From what I saw in that video, in some aspects her jumps look better than GG's, technique-wise. Actually, I think she may develop into a very solid and consistent jumper, if she survive changes in her body.
